I am using the Samsung i9220 android system 2.3.5The precondition for this information leakage is that the mobile phone has enabled the screen unlocking setting function and is bound to a google account or password protection.By default, you need to enter the unlock password or pattern after the mobile phone locks the screen to enter the mobile phone.Below is my
the password document.
The rationale for this approach is similar to what we discussed earlier about cracking Windows passwords, where the password for the PC system exists in Sam, and the Android system password exists in the Password.key file. Users who have root systems or brushes are supposed to know about the ADB, right? So, if we can delete this file, the Android password will be solved!

Getdeviceid (); String IMEI = secure.getstring (Mcontext.getcontentresolver (), secure.android_id); return imei; }The disadvantage of this approach is that:1. Users who encounter high security alertness, I do not accept this permission, do not install your app.2.
